# Problem 1 # Suppose a point-mass particle with mass, 'm', moving in a gravitational potential, 'U(r)', where 'r' is the distance from the center of the potential. A positional vector and momentum vector of a particle are vec r' and "vec p', respectively. (\vec means vector symbol.) Q1) An angular momentum vector vec J' is defined as vec J = \vec r x \vec p. Show that \vec J is conserved in such a gravitational potential U(r) which depends...

14.8. Kepler motion: In an appropriate coordinate system, the motion of a planet around the sun (considered as fixed) with the attractive force being propor tional to the inverse square of the distance z of the planet from the sun is given by the solution of the second-order conservative system with the potential function-İzl-1 for: * 0.

The effective single particle of reduced mass u has an elliptical orbit whose energy is an increment AE above the minimum energy Vmin for a closed orbit. Find the angular momentum and pericenter radius rmin as a function of AE and Vmin- b. An impulsive force is applied to the effective particle at its pericenter, reducing the angular velocity to a factor k times...

The potential energy of a particle in Earth's central gravity field is: V The negative sign arises because the gravity potential is defined as zero at r-o The resulting equations of motion should be the same as those in problem 4.

Two stars, each of mass M, orbit around their center of mass. The radius of their common orbit is r (their separation is 2r). A planetoid of mass m (<< M) happens to move along the axis of the system (the line perpendicular to the orbital plane which intersects the center of mass) as shown in the figure. a. Calculate directly the force on the planetoid if it is displaced a distance z from the center of mass (you’ll need...

Hi there can you please answer question part (b) (ii) - thank you Consider a test particle of mass m orbiting in a Schwarzschild black hole of mass M. If the particle orbits at a speed uc and at a distance r > ., where c is the speed of light and . = 2GM/? the Schwarzschild radius, we can use the usual Newtonian central force equations of motion to analyse the orbit. The effective potential, however, needs to be...
